Types of azeotropes:
Minimum boiling azeotrope
The non- ideal solutions showing positive deviation form minimum boiling azeotrope at a specific composition.
Example: 95% ethanol and 5% water (by volume)
Ethanol = 351.3 K , Water = 373 K, Azeotrope = 351.1 K
Maximum boiling azeotrope
The non- ideal solutions showing negative deviation form maximum boiling azeotrope at a specific composition.
Example : 68% Nitric acid and 32% water (by mass)
Nitric acid = 359 k, water = 373 k, Azeotrope = 393.5 K
